Detailed Description

Macro Definition Documentation

◆ SIP_CALL_INFO_INIT

#define SIP_CALL_INFO_INIT ( )

Initializer for structure sip_call_info_t.

A static sip_call_info_t structure for Call-Info header must be initialized with the SIP_CALL_INFO_INIT() macro. For instance,

#define SIP_CALL_INFO_INIT()
Initializer for structure sip_call_info_t.
Definition sip_protos.h:5860
#define sip_call_info(sip)
Access a SIP Call-Info header structure sip_call_info_t from sip_t.
Definition sip_protos.h:5843
Structure for Call-Info header.
Definition sip.h:449

◆ SIPTAG_CALL_INFO

#define SIPTAG_CALL_INFO (   x)

Tag list item for pointer to a Call-Info header structure sip_call_info_t.

The SIPTAG_CALL_INFO() macro is used to include a tag item with a pointer to a sip_call_info_t structure in a tag list.

Parameters
xpointer to a sip_call_info_t structure, or NULL.

The corresponding tag taking reference parameter is SIPTAG_CALL_INFO_REF().

◆ SIPTAG_CALL_INFO_STR

#define SIPTAG_CALL_INFO_STR (   s)

Tag list item for string with Call-Info header value.

The SIPTAG_CALL_INFO_STR() macro is used to include a tag item with a string containing value of a sip_call_info_t header in a tag list.

Parameters
spointer to a string containing Call-Info header value, or NULL.

The string in SIPTAG_CALL_INFO_STR() can be converted to a sip_call_info_t header structure by giving the string s has second argument to function sip_call_info_make().

The corresponding tag taking reference parameter is SIPTAG_CALL_INFO_STR_REF().

Function Documentation

◆ sip_call_info_copy()

sip_call_info_t * sip_call_info_copy ( su_home_t home,
sip_call_info_t const *  hdr 
)
inline

Copy a list of Call-Info header header structures sip_call_info_t.

The function sip_call_info_copy() copies a header structure hdr. If the header structure hdr contains a reference (hdr->h_next) to a list of headers, all the headers in that list are copied, too. The function uses given memory home to allocate all the memory areas used to copy the list of header structure hdr.

Parameters
homememory home used to allocate new structure
hdrpointer to the header structure to be copied

When copying, only the header structure and parameter lists attached to it are duplicated. The new header structure retains all the references to the strings within the old hdr header, including the encoding of the old header, if present.

Example
call_info = sip_call_info_copy(home, sip->sip_call_info);
sip_call_info_t * sip_call_info_copy(su_home_t *home, sip_call_info_t const *hdr))
Copy a list of Call-Info header header structures sip_call_info_t.
Definition sip_protos.h:5990
Returns
A pointer to newly copied header structure, or NULL upon an error.

◆ sip_call_info_dup()

sip_call_info_t * sip_call_info_dup ( su_home_t home,
sip_call_info_t const *  hdr 
)
inline

Duplicate a list of Call-Info header header structures sip_call_info_t.

Duplicate a header structure hdr. If the header structure hdr contains a reference (hdr->x_next) to a list of headers, all the headers in the list are duplicated, too.

Parameters
homememory home used to allocate new structure
hdrheader structure to be duplicated

When duplicating, all parameter lists and non-constant strings attached to the header are copied, too. The function uses given memory home to allocate all the memory areas used to copy the header.

Example
call_info = sip_call_info_dup(home, sip->sip_call_info);
sip_call_info_t * sip_call_info_dup(su_home_t *home, sip_call_info_t const *hdr))
Duplicate a list of Call-Info header header structures sip_call_info_t.
Definition sip_protos.h:5947
Returns
A pointer to the newly duplicated sip_call_info_t header structure, or NULL upon an error.

◆ sip_call_info_format()

sip_call_info_t * sip_call_info_format ( su_home_t home,
char const *  fmt,
  ... 
)
inline

Make a Call-Info header from formatting result.

Make a new sip_call_info_t object using formatting result as its value. The function first prints the arguments according to the format fmt specified. Then it allocates a new header structure, and parses the formatting result to the structure sip_call_info_t.

Parameters
homememory home used to allocate new header structure.
fmtstring used as a printf()-style format
...argument list for format
Returns
A pointer to newly makes header structure, or NULL upon an error.

◆ sip_call_info_init()

sip_call_info_t * sip_call_info_init ( sip_call_info_t  x[1])
inline

Initialize a structure sip_call_info_t.

An sip_call_info_t structure for Call-Info header can be initialized with the sip_call_info_init() function/macro. For instance,

sip_call_info_t * sip_call_info_init(sip_call_info_t x[1])
Initialize a structure sip_call_info_t.
Definition sip_protos.h:5878

◆ sip_call_info_make()

sip_call_info_t * sip_call_info_make ( su_home_t home,
char const *  s 
)
inline

Make a Call-Info header structure sip_call_info_t.

The function sip_call_info_make() makes a new sip_call_info_t header structure. It allocates a new header structure, and decodes the string s as the value of the structure.

Parameters
homememory home used to allocate new header structure.
sstring to be decoded as value of the new header structure
Returns
A pointer to newly maked sip_call_info_t header structure, or NULL upon an error.

◆ sip_is_call_info()

int sip_is_call_info ( sip_header_t const *  header)
inline

Test if header object is instance of sip_call_info_t.

Check if the header class is an instance of Call-Info header object and return true (nonzero), otherwise return false (zero).

Parameters
headerpointer to the header structure to be tested
Return values
1(true) if the header is an instance of header call_info
0(false) otherwise

Variable Documentation

◆ sip_call_info_class

msg_hclass_t sip_call_info_class[]
extern

Header class for Call-Info header.

The header class sip_call_info_class defines how a SIP Call-Info header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_call_info_t header structure.
